Bitcoin Was the Best Investment of the Decade.

No. It was potentially the most profitable. That is not nearly the same thing as “best.” When one considers investments, these are some of the factors one must assess: risk, potential returns, volatility (beta), fungibility, liquidity and usefulness, the time horizon and security.

There are others; those are not the only ones. However, Bitcoin fails on the most of these measures. If you were lucky enough to get in early it was probably profitable. But as an investment, it’s terrible in most ways that matter.
